Glad to help. Yeah 10 seconds is a bit longer than you might expect to enter a pairing mode. I still love this 4 button device.

So in Home Assistant, if you go to "Settings" > "Integrations" and click the "Zigbee Home Automation" icon, then press "Configure". You should now see a screen with 3 tabs at the top. At the bottom of the "Network" one (which it defaults to) you will see the 2 settings. In ZHA you have to define the durations in seconds, whereas in Zigbee2Mqtt it's in minutes. To analyse the Zigbee network channels I have used the web browser built into the SMLight Coordinator dongles. However, I believe at the moment when using the Ember firmware the scan functionality doesn't work. I ran a scan before I upgraded the firmware from EZSP to Ember. To scan WiFi channels I have used both the "WiFiman" app and the functionality built into my UniFi access points. The thing with scans though is that things can change. Your neighbours might have normal router which switch channels randomly based on what it thinks is a clear channel at that moment in time. The Zigbee channels 15 & 20 somewhat between WiFi channels so the best you can do really.

I'm not sure; so I asked ChatGPT, which suggests that exponential is more appropriate in this instance. Either way, the point I'd like to get across is that adding distance really has quite an impact on signal strength, as some people may otherwise think that placing your device 14 meters away rather than 7 meters only means half the signal strength, but indeed has a lot more impact than that. Thanks for watching and commenting, appreciated!

​@@lets-automate Well, do not trust anything a chatbot may respond. What you may be thinking of is the "inverse square law" which means that the signal strength, light level, sound pressure ... decays proportional to the distance squared. en.wikipedia.org/wiki/Inverse-square_law en.wikipedia.org/wiki/Free-space_path_loss I perfectly know your point but claiming that it is "either way" can imply that someone is not interested in knowledge, learning and correcting something wrong. The difference is actually massive. Examples: - linear growth: 1, 2, 3, 4, 5, ... - quadratic growth: 1, 4, 9 ,16, 25, ... - EXPONENTIAL growth: 1, 10, 100, 1000, 10000, ... PS. I have a well founded degree in mathematics and computer science

Thanks for the comment! I'm sure there's plenty of advice I've missed too!

Comment appreciated. Yes, it's a minefield!

Yes they are supposed to. Although some battery powered end devices may take a while to realise the router is offline as they don't communicate often to save on battery. So trying to keep them online is your best bet!

Correct, you don't lose your data when updating TrueNAS. I was just mentioning that when you update the ZFS file system then there is a small risk that there could be a bug in the update that leads to data loss (there was an instance of this as early as last year), so having your data just on 1 system is always a bit risky and wise to have a 2nd TrueNAS instance or Cloud backup etc. And for sure you're right that if you enable encryption (which you generally should) then make sure your keys are backed up in multiple places too!

I think as a starting point most ESP32 boards are worthwhile. For example this one on AliExpress: s.click.aliexpress.com/e/_DC4UXyh This has 2 listings, one for the ESP32 itself and then an optional development which can be a nice way of easily attaching wires to the GPIO pins. Please note this is an affiliate link so I would get a few pence if you used it, but you can also just search for "ESP32" on Aliexpress. There are so many sellers I can't guarantee what they are like, but I've ordered a lot from Aliexpress and thankfully never really had an issue. Hope this helps!

To be honest it doesn't really matter if you say "from" or "to". People would probably more commonly say "to" just because that is the thing being powered. In reality, in an AC circuit the electron direction keeps changing.

Long winded answer...my channel audience is a bit split and so some videos have been struggling. This video was not doing well for a long time and so my priority for the next video on TrueNAS was low. This video has shown a lot more interest recently so I will for sure move it up the list. I have a few others first but will then pick this up again!

Your nice comment is really appreciated! Thanks.

If it's been raining then the soil moisture sensor will go up so I don't think a rain sensor is needed. I would however like a weather station, but good ones are quite expensive.

如果是为了生意，那么可能是的。感谢您的观看。

This video is about allowing you to expose Node-RED nodes in Home Assistant. The left menu item is the Node-RED add-on which I'm assuming is already installed / in use. By default you get access to Home Assistant entities in Node-RED but not the other way around. So this shows you what you need to install to expose Nodes in HA. Hopes this helps clarify.

Ah. I haven't updated to the latest version but they have changed service call to action in Home Assistant so yeah it's probably been changed in the latest Node-RED add-on version too.

Yes, the HA docker version is limited. I prefer using the full HA OS to benefit from add-ons. There are quite a few add-ons becoming important to HA for voice such as, Matter Server, openWakeWord, Piper.

I just used Ubuntu Desktop, but I would suspect either would be fine.

Yeah, Postman is great for development and testing of API calls, but if you want to Automate the API calls then Node-RED is great for this.

I will go check but it was unreasonable to me. Like 4 to 5 seconds. The Aqara buttons it's more like 2 seconds which is okay.

Totally agree, if you don't need it then best to have stuff in all one place. In my case, I certainly have some things that would be extremely difficult to achieve in HA. There is a lot of the stuff which used to be hard to do in HA, but I have now migrated most of those automations back from Node-RED into HA.

I think Techno Tim did a video on that, I need to check it out for sure.

Hi, sorry for the late reply! Yes you will want to have the M3 Hub to integrate it into Home Assistant. Another option is to use something like a Sonoff Dongle running Thread, but this is still a bit complex at the moment. Also, it's worth noting that since doing this video I have actually had a few times where the lock state loses synchronization between the lock and Home Assistant, which is really not great. And sometimes I have needed to recalibrate the lock. I was hoping that Aqara would have released an updated firmware by now with some bug fixes, but they have not, it's still firmware version 65. My SwitchBot Pro lock on the other hand is definitely not as nice locking, but this has been much, much more reliable in terms of sending state changes and never needs recalibration. (This is also the case for their original SwitchBot lock)

Incase. You got homepod u can use it via matter

@@lets-automate i have the sonoff dongle P. Reading up on it to run both zigbee and thread i need thr E version.

Hi there! You don't need to create an empty payload node anymore really, this is a hangover from old versions which caused issues in some situations. You can just drag multiple lines to a node without anything in the middle. However, if you right click on a node > Insert > Junction then this can be useful to join things together and tidy things up. Hope this helps!

Hi! It depends on what you are using them for. If you are just using them to trigger automations with either Apple Shortcuts of Home Assistant then pretty much any NFC Tags you can buy from Amazon will work as all they store is a unique id. They are usually MiFare Classic 1K, which will be fine. You can also use these to store URLs, contact details or WIFI connection details.

Yeah it's quite neat and can get into spaces my others can't. As will all of these things though in a couple of years time they'll probably be much better again and hopefully eventually hoover my stairs!
